Abstract: A hydraulic circuit for a power transmission device has an oil passage supplying hydraulic pressure of hydraulic fluid to the power transmission device mounted on a vehicle and a hydraulic actuator on which the hydraulic pressure of the hydraulic fluid in the oil passage acts, the oil passage is provided with a concave portion of the inner surface of the oil passage that is recessed upward in the state of mounting on the vehicle. The concave portion is located upstream of the hydraulic actuating portion in the oil passage and above the hydraulic actuating portion when the unit is mounted in the vehicle.

Abstract: A temperature detecting material comprises a first material containing a first temperature indicating material and a second material containing a second temperature indicating material, wherein the first temperature indicating material and the second temperature indicating material contain a leuco dye, a color developing agent, and a decoloring agent, and have a hysteresis characteristic in their color density-temperature curves, wherein the first temperature indicating material has a color developing temperature in a temperature increase process lower than a decoloring temperature in the temperature increase process, and turns to a non-crystalline state and is kept in a decoloring state when cooled down below the color developing temperature in the temperature increase process with a predetermined cooling speed or more after melting, wherein the second temperature indicating material, a color developing temperature is lower than a decoloring temperature in the temperature increase process, and wherein the co

Abstract: A hydrotalcite is represented by formula (1): (M2+)1-X(M3+)X(OH)2(An?)X/n·mH2O??(1), wherein M2+ indicates a divalent metal, M3+ indicates a trivalent metal, An? indicates an n-valent anion, n indicates an integer of 1 to 6, 0.17?x?0.36, and 0?m?10. The hydrotalcite has (A) a lattice strain in the <003> direction is 3×10?3 or less as measured using an X-ray diffraction method; (B) primary particles with an average width between 5 nm and 200 nm inclusive per a SEM method; and (C) a degree of monodispersity of 50% or greater (degree of monodispersity (%)=(average width of primary particles as measured using the SEM method/average width of secondary particles as measured using a dynamic light scattering method)×100). A resin containing the hydrotalcite, a suspension containing the hydrotalcite and a method for producing the hydrotalcite are disclosed.

Abstract: A support position adjustment amount estimation apparatus includes a reference load data storage storing reference load data for each support device obtained when a reference surface of a machine tool is in a leveled condition, a relational equation storage storing a relational equation between an amount of variation of a support position in each support device from a reference support position and an amount of variation of a load in each support device from the reference load data with the support position in one support device selected from three or more support devices fixed, and an adjustment amount estimator estimating a support position adjustment amount for each support device other than the fixed support device based on load data detected in all of the support devices, and the reference load data for all of the support devices, and the relational equation.
